Application July 18, 1946, Serial No. 684,524

1 Claim.

My present invention relates to an improved nail puller and more particularly to a nail pulling tool especially adapted for use in extracting nails from shingle sidings, and other items where it is desirable to have available means for removing the retaining nails without damaging the object so held.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claim.

In the drawings:

Figur 1 is a side elevational view of the nail puller of my invention.

Figure 2 is a top plan view thereof with the handle cut away.

Figure 3 is a rear elevational View.

Referring now to the drawings wherein like characters indicate like parts, I have illustrated the tool of my invention consisting in a hearing plate 2, an elongated stifi metal strip bifurcated at the rear end to form sections 4 and 5 with the intermediate slot or notch 8. The outer extremities of the sections 4 and 5 are beveled or tapered as at 9 to facilitate the insertion of the tool under the head of the nail to be extracted.

Forward of the bearing plate I have provided an opening l formed with forwardly and rearwardly extending. and converging slot l2.

The forward extremity of the bearing plate 2 is bifurcated to form sections l4 and IS with the intermediate slot l8 while the leading edges of the bifurcated sections are beveled as at It.

Lateral shoulders 20 are spaced from the bearing plate proper by slots 22, and the shank 24 provides for the mounting of the handle 26, substantially cylindrical in shape, the forward and rear terminals being scored as at 28 and 30, and under the handle is provided the claw 32.

In removing shingles or siding from a buiding it is desirable to effect the removal with as little damage as possible to the shingles or siding, and the tool of my invention is designed to accomplish thos purposes.

The rear nail puller embodied in the bifurcated sections 4 and and the slot 8 is employed to remove the exposed nail on a shingle by placing the beveled side sections about the nail and under the head and then lifting the handle or rocking the same on its fulcrum F. When the nail has been partially extracted, the claw 32 may be employed to finish the removal of the The shoulders 20 and slots 22 are employed under the shingle and the nail is extracted after the nail is engaged in the slot'by striking the end 28 of the handle with a hammer or similar tool.

The forward pulling element may be employed by placing the slot adjacent the nail and striking the end 30 of the handle, while the central opening I0 and slots I2 may be used to pull nails with broken or distorted heads. The handle may be struck at either end when the broken nail is within the opening I 0 and the converging slots or wedges l2 will extract the nail.

From the above description of the construction and operation it will be apparent that the tool of my invention will provide for all contingencies which may arise in the removal of shingles and siding, and the various co-operating elements for a combination of nail extracting means in a single tool.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

A nail pulling tool comprising a bearing plate having a lower fulcrum, a vertical shank and a handle on the shank extending rearwardly of said shank, said shank being formed on said plate slightly forward of said lower fulcrum, bifurcations at the opposite ends of the plat for selected engagement with a nail for the partial, extraction thereof, the underside of the bifurca tions at one end of the plate being beveled upwardly to form the lower fulcrum, lateral shoulders on the plate and spaced therefrom forming nail engaging slots therebetween, a central opening having communicating slots formed with converging walls, and a nail removing claw on the handle.

STANLEY SCHWORK.
